BACKGROUND OF THE INVENTIONThis invention relates to an apparatus for treating rodents particularly wild rodents with a chemical substance. In some instances, treatment of wild rodents can be beneficial to the public health. It is an object of the invention to provide an apparatus that can be placed in an outdoor area to treat wild rodents in the area with a chemical substance.
SUMMARY OF THE INVENTIONAccording to the invention there is provided an apparatus for applying a chemical to rodents. The apparatus includes an enclosure having at least one peripheral opening for allowing entrance of rodents into the enclosure. The enclosure includes at least one applicator in the form of a suspended flexible web arranged to contact rodents entering the chamber and having the chemical on the web.
For a better understanding of the present invention, together with other and further objects, reference is made to the following description, taken in conjunction with the accompanying drawings, and its scope will be pointed out in the appended claim.
Referring to
Lower member 12 includes sidewalls openings 28 which are visible in the side view of
In the embodiment shown in
It will be understood by those familiar with the art that different size, shape and configuration of enclosures may be use in accordance with the invention and that the particular location of applicators 32 in such enclosures may be at different locations according to the arrangement of passages in the enclosures.
It should be additionally recognized that it may be advantageous to provide applicators 32 in a configuration wherein they can be easily replaced with new applicators to provide a renewed supply of chemicals.
The applicator 32 of
An alternate applicator 43 shown in
Applicators 32 and 43 may be arranged so that their respective webs pass through slots 26 while the support rods engage the top wall 14 of the enclosure.
Another version of applicator 50 shown in
Alternatively, a horizontal support bar 62 may be provided across a passageway as shown in
Applicator 80 shown in
Applicator 90 shown in
Claims
1. An apparatus for applying a chemical to a rodent, the apparatus comprising:
- an enclosure with at least one peripheral opening to allow entry of the rodent into the enclosure;
- an interior passageway adjacent the at least one peripheral opening;
- an inner chamber for receiving bait to encourage the rodent to enter the enclosure through the at least one peripheral opening;
- an interior opening connecting the interior passageway to the inner chamber; and
- one or more applicators with the chemical applied thereon, the one or more applicators being positionable within the interior passageway of the enclosure between the at least one peripheral opening and the bait and extending from a top of the passageway to a bottom of the passageway to substantially obstruct the passageway,
- wherein the one or more applicators comprise a flexible portion that can flex when contacted by the rodent, thereby allowing the rodent to move past the one or more applicators
- wherein the enclosure comprises a top wall, and at least one applicator is configured to be suspended from the top wall in the interior passageway between the at least one peripheral opening and the interior opening and at least one applicator is configured to be suspended from the top wall in the inner chamber between the interior opening and the bait,
- wherein the one or more applicators comprise an upper horizontal support member and the flexible portion of the one or more applicators comprise a fabric suspended from the support member, and
- wherein the top wall of the enclosure comprises a plurality of slots that comprise openings that pass through the top wall of the enclosure for receiving applicators, the horizontal support member being larger than the slot to suspend a respective applicator from the top wall.
2. The apparatus of claim 1, further comprising an interior wall between the interior passageway and the inner chamber.
3. The apparatus of claim 1, wherein the fabric includes a plurality of slits to allow passage of the rodent through the fabric.
4. The apparatus of claim 1, wherein the enclosure comprises a first peripheral opening and a second peripheral opening, the first and second peripheral openings being at opposite ends of the interior passageway.
5. The apparatus of claim 3, wherein the fabric comprises a flexible web.
6. The apparatus of claim 1, wherein the fabric includes a plurality of cutouts.
7. The apparatus of claim 6, wherein the plurality of cutouts are triangular in shape.
